MOSCOW, December 30. /ITAR-TASS/. The Russian Navy's two nuclear-powered submarines, the Yuri Dolgoruky and Alexander Nevsky, arrived at the restricted-access administrative and territorial unit Gadzhiyevo (Murmansk Region) where the Northern Fleet (NF) submarine forces are based, a spokesman for the Russian Defense Ministry's press-service and information department for the Navy told journalists on Monday.

"On December 30, strategic nuclear-powered missile-carrying submarines, the Yuri Dolgoruky and Alexander Nevsky, of Design 955 Borei (Boreas) have arrived at the NF's basing point of Gadzhiyevo," the Navy official said. The submarines had left the OAO (public joint-stock company) Sevmash (in Severodvinsk) on December 28.

"It is planned that the missile-carrying strategic submarine cruiser Alexander Nevsky, which has been phased into service with the Navy, will soon begin to set about practicing course-unit missions in preparation to join permanent-readiness forces," the officer pointed out. He added that the Yuri Dolgoruky nuclear-powered submarine has passed a routine dock inspection at the Sevmash enterprise and will not continue to accomplish missions under the plan of the Command of the NF submarine forces.

The Alexander Nevsky, the first serially made ship of Design 955 Borei, was fazed into service with the Navy on December 23. Its keel had been laid on March 19, 2004. The type ship of this design — the Yuri Dolgoruky — was phased into service in January 2013.

The keels of another two serially made ships of this design, the Vladimir Monomakh and the Knyaz (Prince) Vladimir were laid at the Sevmash in 2006 and 2012. In all, eight Borei-class submarines are to be built within the period until 2020.
